# Expert Advice:

01 -
  • Theres something deeply satisfying about waking up to breakfast thats already handled, waiting in the fridge like a gift from past-you
  • The protein keeps me full for hours, which means no mid-morning stomach growling during meetings
02 -
  • The first time I made this, I used quick oats and woke up to what was essentially cold glue—old-fashioned rolled oats are non-negotiable for texture
  • Protein powder brands vary wildly in how thick they make things—start with less liquid than you think you need, then add more in the morning
03 -
  • Mix your peanut butter with a little warm milk before combining it with everything else—it incorporates so much more smoothly
  • If the protein powder taste bothers you, use flavored vanilla instead of unflavored, or add an extra half teaspoon of vanilla extract
